Integer with 24 digits

Question

To check some bank account numbers I want to do a modulo 97 on an account number. But a lot of account number is to big to enter in a UInt64. How can I do an opperation on a 24 digits integer ? Thanks, Sample code (it can't convert) : ``` (Convert.ToUInt64("756842356987456214536254") % 97 == 1); ```

Accepted Answer

One way would be to use `System.Numeric`'s `BigInteger`:

```
BigInteger bi = BigInteger.Parse("756842356987456214536254");
```
